.HUB-DooKING DEVICE FOR In my companion application iiledvunderv even date, thereis disclosed a novelwire wheel adapted for mountingron the end of an axle, and ordinarily a nut, hub cap or locking device in Fig.v 5.

other device is mounted on the outer end of the 'axle to' retain the wheel thereon` On account ot' the wheel being subjected to -lat-V eral stresses and strains there is a tendency for the wheel holding devices to become de- `tached and this often results inv al serio-us accident. Y l Y ,l

The primary object of this invention is to )rovide la locking device by which a wheel hu may be positively retained on the axle, against lateral displacement, yet permit of the wheel. being easily and quickly demounted at will. I

i Another object otthis invention 'is to'proyvide a locking device embodying three members constructively arraneed'and joined so that any tendency of either of two of said members to become displaced is resisted by the other of the two of said members, and

in consequence of this novel arrangement, it is practically impossiblefor stresses and strains, vibrations or the rotary action of one member relative to another to cause dislodgment of the locking device. l

A further object ot this invention is kto provide :i simple, durable andinexpensive locking device capable ofgeneral use, and the construction entering into thev device will be hereinafter specically described and then claimed.

Reference will now behad to the drawing,A

wherein' n Figure1 is a longitudinal sectional view of a wheel'hub provided with a locking device; y i Fig. 2 is a longitudinal sectional view of a detached intermediate member;

Fig. 3 is aV longitudinal sectional view of an inner member; Y

Fig. 4 is a similar view oi an outer member.

Fig. 5 is a longitudinal sectional view of a wheel hub showing anotherfform of locking device; Y i

Fig. 6 is a view of the outer face ot' an intermediate member, and

Fig. 7 is a cross sectional view of the In the drawing the reference numeral 1 denotes, by the way of an example, the end of a tubular axle having a brake drum 2,a

i demountable hub 3, and spokes fl supporting Toretain the demountable wheelhub Son the axle 1,' the outer end otthe axle is provided with an vinner. member which-,is

riveted or, otherwise fixed, vas at 7,`to the axle 1 -adjacenttheouter ,endfther'eot The i inner member 6' hasya'collar 8 intermediate fthe ends thereof and adaptedv to abutl the Y.

end of the Vtubular axle with lapproximately half of the inner member within the tubuiar axleto firmly brace the walls thereoffand afford a substantial 'connection between the axle and the inner member. That vportion oi' the inner member protruding`l from the tubu! `lar axle'. has `exterior 'Screw lthreadsot' a greater pitch thanthe interiorscrew threads 10. The difference in pitch vor lrind isvessen tial, as will hereinafterappear. 'n l abutting the-outer'ends of the hub 3 isl a gasket 11' andengagingv the vgasket 11 is the peripheral tool engaging iiange 12 of an intermediate member 13, .which is interiorly screw-threaded, Vasfat 14, so that itmay be `screwed on the `exteriorthreads9 of the inner member6-` Zlheouterl wall oi theintermediate member 13 isl v, tapered l outwardly towards the "outer end of `*said intermediate member to formv a conical seat 15, best shown inFi`g.2. v' v' l:

r*To prevent accidental rotation ofthe. 1ntermediate member 13 on the inner member 6,'an outer cap-lil e member 16y is employed.

y This 'member has a central'` hollow boss 17 with its interior wall provided with 4screw-y threads 18, said, screw threadscorrespond# ing to they screw threads 1'() ofthe inner .i

member 6',y so that the Vboss 17 canbe screwed into the inner member 6. rllheouter member ythe conical seat 15 of the intermediate member 13, and it is by rvirtue ot said contacting wheel hubB, it will tend to rotatethe outer: f

member 16, by reason of the contacting seat 15, and the Wall '20, but since .the pitch of the screwthreads 1.0 and 18 dlterent from V13 andbecome detached,- and since the douter,

member is only underl the intluenceot the ,Y intermediate member,A the .outer member serves asa lock` orthe intermediatemeinber, yetpermits ,etL the member being' re-r moved' atwill when voccasion so requires. Y

Reference will now'behad ltok Figs. 5 te 7 inclusive.Y wherein 25 isan inner member interiorlyjscrewthreaded to-receive an outer member 26 and'eXt-eriorly screwthreaded to 'receive an intermediate member 27, there be ing-a difference of about two threads between the threaded portions of the inner memben The intermediate member 27-has Vfits outer faceprovided .with aseries ol cir'- vcum'lerentially arranged depressions .or ref cesses 28 and Vadapted to engage inthesedepressions are spherical or otherwise shaped' detents 29 arranged ink Apockets-30 formed in'bosses 3lV carried by Vthe outer member '26. In the Vpockets 30 are coiled expansion springs 32 which bear agaii'ist the' detents 29 and hold the detents in env'aement with the intermediate'member 27, yet permit. oi' said detents' yielding as the outer member vis rotated relative tothe other members. The outer member 26 has a peripheral flange 353 which; bears against tlieintermediate member 2.7 ,and this locking' device is structurelb,v ditl'erent from the 'device' previously de# scribed, but involves the same locking` prin-- Vciple in addition to the detente 'which serve as lockingV means for securing the outer member against rotation. f

lItis thought that the utility oiz my locke ing device .will beA apparent without 'furthe-r description, and while in the ,drawing there is lillustrated the lpreferred embodiment of my invention', in connection with a wheel hub, yet it is to be understood that the in; terlocking` `members are vsusceptible oit' general use and such structural changes as lare permissible bythe appended claims.

Vhat I claim is i l. The combination with an axle and ka wheel hub detachably mounted thereon, ot an inner member attached to said aille, an

intermediate member screwed on said inner 'member to ret-ain said'wheel hub on said axle, and an outei memberr screwed in said inner member and against said intermediate member. l i j 2.`The Vcombination called for in'` claim l, wherein Vthe 4screwv connection between said inner and intermediate members :is of greater pitchthan the screw connection between said inner (andV outer members.

3. The combination called for in claim l,

"wherein .said intermediate member'has a" conical seat tor a wall of said outer member,
